It's a bit nuanced, but I guess you're right. There's the librecore thing - but AFAIK they didn't reach out to coop the other developers, they didn't publish their own builds, and the inertia was lost. What could be the straw that breaks the camel's back - would be for Leah to piss off Paul Kocialkowski, as he's the guy who wrote a big chunk of libreboot (especially the newer parts of the system, with the chromebooks); But time will tell.
